RL78/D1A CHAPTER 4 PORT FUNCTIONS
(4) Port input mode registers (PIM0, PIM1, PIM3, PIM5 to PIM7, PIM13)
These registers set the input buffer of P01, P10, P11, P17, P31, P50 to P52, P55 to P57, P61, P63, P70, and P135 in
1-bit units.
Schmitt1 input buffer can be selected during serial communication with an external device of the different potential.
These registers can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears these registers to 00H.
